Beyond Purdue: What Comes Next for Industrial Networks.

A practical roadmap for securing modern industrial networks — without costly rebuilds.

Download the Whitepaper

For decades, the Purdue model provided a structured way to secure industrial systems. But today’s connected operations - cloud, remote access, IT/OT convergence - have rendered its assumptions obsolete. The result? Flat, brittle, and overexposed networks.

This whitepaper explores:

  • Why the Purdue model is failing in practice.

  • The principles of a “Beyond Purdue” architecture: identity-first, software-defined segmentation, and enclaves.

  • How manufacturers can modernize incrementally through overlays.

Why Read It?

  • Learn how to protect legacy assets without rip-and-replace.

  • Discover how enclaves simplify cross-layer security.

  • Get a blueprint for resilient, software-defined industrial networks.

Overlay Networking

Secure and segment an existing infrastructure — without touching the underlying physical network.
